FUNCTIONS

SWITCHING ON/OFF

1. Press the green ON (I) button to start the band saw.
2. Press the red OFF (O) button to stop the band saw.
NOTE: The blade may continue to
rotate for a short time before coming to a complete stop.

UPPER BLADE GUARD ADJUSTMENT

1. Rotate the blade guard adjustment knob:
• Clockwise to raise the blade
guard.
• Anti-clockwise to lower the
blade guard.
NOTE: The blade guard should be
positioned as close as possible to the top of the material the blade is cutting.

USING THE FENCE

• The rip fence can be used on
both sides of the blade.The scale indicates the distance from the saw blade to the fence.
1. Place the fence over the guide rail. and into the required position. and then press down the lock lever to clamp the rip fence in position.
WARNING: Always use a push stick when straight cutting small work pieces using the fence;
12
Page 13

USING THE PUSH STICK

• The push-stick serves as an extension of the operators hand as
protection against accidentally touching the saw blade.
• The push-stick should be used if the distance between the blade and rip
fence is less than approx 150 mm.
• Always replace the push-stick if lost or damaged.

USING THE MITRE GAUGE

1. The mitre gauge is inserted into the table slot from the front edge.
2. To set a mitre angle, loosen the locking knob by turning it counterclockwise.
3. Firmly tighten the locking knob to secure the mitre gauge in position.

TILTING THE TABLE

1. Loosen the table tilt clamp.
2. Adjust the table to the required angle.
• We recommend that you use a
protractor to ensure accuracy.
3. Retighten the table tilt clamp.
NOTE: The scale and pointer can
be adjusted by loosening the screw on the pointer.

OPERATION

Before commencing work, ensure the work area is clean and tidy and the bandsaw table is clear of tools etc. Plan your work carefully and set the bandsaw up accordingly before switching on.
1. Check the blade is correctly tensioned before use (see page 17).
2. Set the upper blade guide as close as practical to the workpiece. This provides the best safety for the operator and giving more accurate results and greater control.
3. Switch on and allow the saw blade to reach full speed before proceeding.
• Use both hands to feed the
workpiece. The work must be held flat on the table at all times to prevent the blade from binding
• Use a steady, even pressure,
just sufficient to keep the blade cutting.
• Always use the rip fence or mitre gauge where possible to eliminate any
sideways movement of the work. This is most important when the table is tilted at an angle.
• Remember that the blade removes material during the cut creating a
gap called the ‘kerf’, which must be allowed for when cutting to exact sizes. Plan your cut so that the kerf is the scrap side of the line you wish to cut. Where necessary, allow a little more material for finishing.
• Always use a suitable holding device when cutting round or irregular
shaped timber to prevent twisting of the work piece.

15
Page 16

FITTING A BLADE

WARNING: BLADES ARE NORMALLY SUPPLIED COILED, TAKE CARE WHEN UNCOILING THE SAW BLADE AS THEY HAVE A TENDENCY TO SPRING OPEN.
1. Slide the blade over the wheels,
NOTE: Turning the wheels as you do so makes this easier.
• Centre the blade on the rubber tyres of the wheels.
• Make sure the teeth point down on the right side.
2. Add a little tension to the blade.
3. Turn the upper wheel clockwise by hand to make sure that the blade tracks correctly on the wheels.
• if not see “Tracking the Saw
Blade” on page 17.
4. Slide the lower blade guard to the right.
5. Close and secure the doors.
6. Replace the guide rail.
16
Page 17

ADJUSTING THE BLADE TENSION

CAUTION: TOO MUCH TENSION CAN CAUSE THE SAW BLADE TO BREAK. TOO LITTLE TENSION CAN CAUSE THE BLADE TO MAKE IRREGULAR CUTS
1. Raise the upper blade guide fully.
2. Check the tension by pressing with a finger against the side of the blade, halfway between the table and upper guide.
• The blade should not flex more
than 2 mm.
3. Turn the blade tension knob to adjust tension.
• Turning the blade tension knob
clockwise will increase the tension.
• Turning the blade tension knob
anticlockwise will decrease the tension.

TRACKING THE SAW BLADE

If the saw blade does not run in the centre of the rubber tyre, the tracking needs to be corrected by adjusting the tilt of the upper bandsaw wheel.
1. If required, open the upper and lower doors.
17
Page 18
2. Loosen the tracking control lock and manually rotate the upper wheel, taking care of the sharp blade
3. Turn the tracking control knob clockwise or anticlockwise until the saw blade tracks centrally on the rubber tyre.
4. After adjusting, retighten the tracking control lock and close the doors.

ADJUST THE GUIDE/THRUST BEARINGS AND LOWER BLADE GUIDES

The guide/thrust bearings and the lower blade guides help keep the blade tracking straight and correctly alligned during use. To adjust:
UPPER GUIDE BEARINGS
1. Loosen the two grub screws.
2. Adjust the bearings so that they are approximately 0.5 mm from the blade.
3. Retighten the grub screws.
REAR THRUST BEARING
1. Loosen the grub screw.
2. Adjust the bearing so that it is approximately 0.5 mm from the blade.
3. Retighten the grub screw.
LOWER BLADE GUIDES
